JOHN HEWES, or LEICESTER, ENGLAND.

CREMATOR CR APPARATUS FOR BURNING REFUSE.

SPECIFICATION forming part of Letters Patent No. 371,842, dated October 18, 1887.

Application filed March 16, 1886. Serial No. 195,391. (No model.)

To all whom, it may concern:

Be it known that I, JOHN HEWES, a subject of the Queen of England, residing at Leicester, in England, have invented an Improved Cremator or Apparatus for Burning Refuse, of which the following is a specification.

In the accompanying drawings, Figure 1 is an elevation of a cremator, a-portion of which is removed to show the internalarrangement. Fig. 2 is a section of the cremator through the center of the furnace.

The invention relates to furnaces or appa ratus designed to incinerate refuse matter, such as housegarbage, sewage, &c.; and it has for its object an apparatus of simple construction and provided with means for utilizing the gases evolved during the process of incineration.

The invention consists in the construction of the furnace and the combination of elements therein, substantially as hereinafter described, and as set forth in the claims.

In practice I prefer to support the incinerator or cremator from pillars A or other suit-' able-support at such an elevation as to afford the necessary space for a vehicle of any sort to be run under the retorts to receive the incinerated or burned material therefrom, as shown I in the drawings.

I sewage and other substances being introduced conveyed by'the bell-mouthed pipes I underneath the furnace-grate, and thence pass throughthe grate-bars to the fire, where they torts, through which said retorts extend, as

shown, and so as to provide passages for the heat to pass into the upper chamber.-

A chimney, A,in communication with the upper chamber, L, is arranged at any convenient point of the apparatus to produce the necessary draft.

Q is the furnace, the heat from which passes through the opening in the iiresquare-K to the chamber above, and R is a suitable rod, which operates the valves S in the pipes I to regulatethe supply of hot air or gases to the furnace.

The described construction may be varied in many ways. The retorts O, for instance, may be arranged horizontally within the combustion chamber or chambers, and a perforated pipe or pipes may be arranged in the upper combustion-chamber, L, and connected.

with the pipes F, so that a portion of the gas generated in the retorts may be utilized as fuel in said upper chamber to heat the upper portion of the retorts. This latter arrangement is especially desirable in large apparatus.

' Having now described my invention, what I claim is 1. In an apparatus for treating organic matter, a furnace and a combustion-chamber in comm unication therewith, in combination with a series of retorts provided with charging and discharging valves, said retorts extending through the combustion-chamber and having their charging and discharging ends located outside thereof, and a gas-pipe common to all the retorts connected thereto, whereby the gases generated in the retorts are carried to the combustion-chamber for use as fuel, substantially as and for the purposes specified.

2. In an apparatus for treating organic mat ter, a furnace, a combustion-chamber communicating with said furnace, and a heating ber and communicating with'the combustion-- chamber, substantially as and for the purposes specified.

3. In an apparatus for treating organic matter, the combination of a furnace, a superposed combustionchamber communicating therewith, and a heating-chamber located above the combustion-chamber, of a plurality of vertical retorts extending through the chambers and having their upper charging and lower discharging ends located above and below said chambers, respectively said retorts passing through openings in the partition-wall be- 20 tween the heating and combustion chambers, which openings are of greater diameter than the retorts, a gas-pipe common to all the retorts and connected to the charging end thereof and communicating with the combustion-chamber, and a gas-pipe communicating with the latter chamber and the furnace, substantially as and for the purposes specified.

In testimony whereof I have hereunto set my hand in the presence of the two subscribing 30 witnesses.

JOHN HEWES.
